FitLineToPoints_RANSAC
Header: | AVL.h |
---|---|
Namespace: | avl |
Module: | FoundationBasic |
Approximates points with a line using a RANSAC algorithm.
Applications: Finds a well matching line, but for handling outliers requires a distance threshold that may be difficult to set.
Syntax
C++
C#
void avl::FitLineToPoints_RANSAC ( const atl::Array<avl::Point2D>& inPoints, atl::Optional<const avl::Range&> inRange, atl::Optional<int> inMaxOutlierCount, float inMaxInlierDistance, atl::Optional<int> inIterationCount, atl::Conditional<avl::Line2D>& outLine )
Parameters
Name | Type | Range | Default | Description | |
---|---|---|---|---|---|
inPoints | const Array<Point2D>& | ||||
inRange | Optional<const Range&> | NIL | Determines which array points take part in fitting process | ||
inMaxOutlierCount | Optional<int> | 0 - | 0 | Determines how many outlier points can be present to end the search | |
inMaxInlierDistance | float | 0.0 - | 3.0f | Distance from the output line for a point to be considered an inlier | |
inIterationCount | Optional<int> | 1 - | 42 | Number of iterations; Auto means that all point pairs will be used | |
outLine | Conditional<Line2D>& |
Errors
